shaft seal pump 中文意思是什麼
shaft seal pump
解釋
軸封泵-
Fsb series fluoroplastic alloy pump is composed of pump body, impeller, back cover, seal, support, pump shaft, bearing, coupling, fasten bolt, nut and base plate
Fsb系列氟塑料合金泵由泵體、葉輪，后蓋，密封性，支架，泵軸，軸承，連軸器，吊緊螺栓，螺母，底板組成。 -
The entire rotating assembly shall be designed with sufficient rigidity and balanced to provide for a maximum shaft deflection at the lower seal of 0. 002 " under all operating points between plus or minus 40 % of the flow at best efficiency point ( bef ) on the pump ' s performance curve
整個旋轉總裝都應該具有足夠的硬度，在泵性能曲線最好性能的正負40 %的范圍內，在所有工作點，最大的軸偏差限制在0 . 002英寸內。 -
To ensure the charging pump working reliably, the following measures should be adopted : ( 1 ) adopting modified circular casing to reduce the radial force of the impeller and decrease the seal clearance ; ( 2 ) using radical ribs on impeller and helical sealing on shaft to realize minor pressure differential ; ( 3 ) using back pressure stuffing box to ensure sealing under small packing force ; ( 4 ) adopting self - lubricant flexible graphite stuffing for absorption of solids entering in the graphite in case of leaking
為確保灌注泵可靠工作，提出改進措施： （ 1 ）採用改型環形泵體降低葉輪的徑向力，減小軸封間隙，抑制泄漏； （ 2 ）採用背葉片降低葉片根部壓頭，獲得微壓，使軸封兩端承受較小壓差； （ 3 ）採用螺旋密封降低軸封兩端壓差，在保持微壓的同時避免出現負壓，密封效果更好； （ 4 ）採用反壓式填料密封結構，在很小的壓緊力下，即可保證密封； （ 5 ）採用具有潤滑功效的柔性石墨填料，即使發生軸封泄漏，進入石墨內部的固相顆粒也將隨著石墨的消耗而被鉆井液吸收。
